HKM-797907 Folding Electric Snow Bike

Master winter terrain with precision electric power and trail‑ready engineering.

750W Brushless Hub Motor

Conquer steep inclines and accelerate smoothly with robust rear hub power. Peak efficiency for challenging snowy paths.

48V 12Ah Lithium‑Ion

Extended rides with over 37.3 miles (60 km) range on a single charge. Intelligent battery management for longevity.

Foldable & Snow‑Ready

Compact folding design for easy storage. CST 20‑inch tires and waterproof build tackle winter conditions with confidence.

Lightweight Aluminum Alloy Frame

Engineered from premium 6061 aluminum alloy, the frame strikes the perfect balance between featherlight agility and rugged durability. At just 45.2 lbs (20.5 kg), it’s easy to maneuver yet robust enough for backcountry snow trails. The integrated folding mechanism allows the bike to collapse to a compact 35.4 x 29.5 x 18.1 in (90 x 75 x 46 cm) for effortless storage in an SUV trunk or apartment closet.

The frame geometry is optimized for stability on slippery surfaces, with a lower center of gravity and extended wheelbase. Every weld is precision-crafted and double-passed for strength, while the matte finish resists scratches and corrosion from road salt and moisture.

750W Brushless Rear Hub Motor

Experience instantaneous torque and silent propulsion. The high-efficiency brushless motor delivers a top speed of 20 mph (32 km/h) on flat snow-packed trails, with enough hill-climbing capability to ascend grades up to 15°. The rear hub placement ensures optimal weight distribution, enhancing traction on loose powder.

Three selectable power modes (Eco, Trail, Boost) let you tailor output to terrain, conserving battery on long-distance explorations or unleashing full power for steep, technical sections. The motor’s IP54-rated sealing protects internal components from snow, slush, and water spray.

48V 12Ah Lithium‑Ion Battery

At the core of the HKM-797907 lies a high-density 48V 12Ah lithium-ion pack, delivering a true range of over 37.3 miles (60 km) under mixed riding conditions. Even in freezing temperatures, the advanced battery management system (BMS) maintains stable discharge, preventing sudden voltage drops.

The removable battery design allows charging indoors or at the office, with a full recharge in 4‑6 hours. Smart LED indicators on the pack show remaining capacity at a glance. An intelligent sleep mode preserves battery health during extended storage periods.

Dual Suspension System

Float over frozen ruts and uneven terrain. The front suspension fork offers 80mm of travel, while the rear shock absorber smooths out trail chatter. Together, they dramatically reduce rider fatigue and improve control on icy patches.

Both front and rear units feature adjustable preload, allowing you to fine-tune stiffness based on cargo weight and riding style. The system is sealed against moisture and debris, ensuring consistent performance season after season.

Advanced Disc Brake System

Stop with confidence on ice and packed snow. The bike is equipped with front and rear mechanical disc brakes, delivering consistent braking power in wet, muddy, or freezing conditions. The 160mm rotors shed water quickly and resist fade on long descents.

An integrated motor cut-off switch instantly halts power delivery the moment you squeeze the brake levers, adding an extra layer of safety. The brake calipers are tool-free adjustable, making maintenance a breeze.

Shimano 7‑Speed Drivetrain

Adapt to changing gradients with precision. The 7‑speed Shimano derailleur and trigger shifter provide crisp, reliable gear changes, letting you maintain an efficient cadence whether climbing a snowy hill or cruising on flat pavement.

The wide gear range pairs perfectly with the electric assist, giving you full control over power output and pedal resistance. Sealed bearing pulleys and a rust-resistant chain ensure durability even after repeated exposure to winter slush.

Intelligent LCD Display & Thumb Throttle

The backlit LCD screen keeps vital metrics in clear view: current speed, battery percentage, power mode, odometer, and trip distance. Even in direct sunlight or whiteout conditions, the high-contrast panel remains legible.

An ergonomic thumb throttle lets you accelerate effortlessly without twisting your wrist—a real benefit when wearing thick winter gloves. The control pad is strategically placed for intuitive access, allowing you to toggle assist levels without taking your eyes off the trail.

20‑Inch CST All‑Terrain Tires

Purpose-built for winter. The 20 x 4.0 inch CST tires feature an aggressive, self-cleaning tread pattern that bites into snow and ice while shedding buildup. Their wide footprint increases floatation on soft surfaces, preventing sinkage and maintaining forward momentum.

Reinforced sidewalls resist punctures from hidden rocks or sharp ice. When conditions improve, the low rolling resistance still offers a quiet, efficient ride on pavement, making this bike a true year‑round companion.

IPX4 Water‑Resistant Construction

Ride through rain, sleet, or melting snow without worry. All electrical connections are sealed with rubber gaskets, and the battery compartment features a double‑locking waterproof cover. The motor and controller are potted to resist moisture intrusion.

The frame itself receives an anti‑corrosion treatment before painting, and stainless‑steel hardware is used throughout to prevent rust. This bike thrives in the harsh conditions that sideline ordinary electric bicycles.

Quick‑Fold Design

Transform the bike from full‑size to compact in under 15 seconds. The robust folding hinge at the frame’s center is secured by dual safety locks, preventing accidental collapse while riding. Folded dimensions of 35.4 x 29.5 x 18.1 inches (90 x 75 x 46 cm) fit neatly into most car trunks, RVs, or even crowded garages.

The pedals also fold flat, and the handlebar stem can be collapsed to further reduce the footprint. An integrated magnetic catch holds the frame together when folded, making it easy to carry with one hand using the built‑in grab handle.

Probably the best robot vacuum mop you can buy in this price range
Size: E25 Black
Its pretty solid device. Honestly its so smart that it vaccumed and mopped my bathroom and ofcourse the wet hair stuck on the wet floor wasnt vacuumed the first pass but it then waited for the second pass to pick it up when it was dry. Made my entire house look so clean its actually amazing. It actually mops and get all the corners with dust. One thing thouhh is the side brushes tend to get tangled with hair and thread but uts very snap on snap off brushes so removing the stuck hair is super easy and only sometimes happens. The suction is amazing too its very strong. It moos the floor with clean water with solution so its actually cleaning well. Overall 10/10

The best vacuum cleaner ever!!
Size: E25 Black, Size: E25 Black
⭐⭐⭐⭐⭐ I honestly couldn’t be happier with the Eufy E25. I actually own two of them, and they’ve completely changed my daily routine. After spending a lot of money trying different brands, I finally found one that truly delivers everything I need in a vacuum. The suction power is impressive, it handles pet hair and debris effortlessly, and the mopping feature actually works (not just a light wipe like others I’ve tried). The self-emptying and self-cleaning system is a game changer—it saves so much time and maintenance. Navigation is smart and reliable, and it rarely gets stuck. It covers my floors efficiently and leaves everything noticeably cleaner. I also love how low-maintenance it is overall. If you’re tired of wasting money on vacuums that don’t live up to expectations, this is absolutely worth it. For me, it has truly been life-changing.

Updated 1/28/2020 update 1/17/2020 It's been everything it was advertised to be and more. (Not)
Size: 11S
I called Amazon again today. Explained the situation and that no one from Amazon or Eufy had returned my calls as they promised. Also after replacing the battery at my own expense it ran 90 minutes again but got stuck everywhere, made this weird ratcheting type noise every time it changed surfaces and finally today just beeped at me twice and died. Supposedly that indicates a seized brush but they all spin freely. This time I just flat out asked them to look at my Amazon account and replace it, as I'm a very good customer. New one will be here tomorrow. I'll do a separate review on that one as it took me forever to find this one again. I'll also let you know if it's a refurbished unit or not. Well wouldn't you know it. I leave a nice review and a few days later, Murphy's law rears it's ugly head. Device is 3 months old a couple weeks out of the exchange warranty and the battery is shot. Runs 5 or 10 minutes on a full charge. Called Amazon to see if since I am a really long standing customer if they'd help me out. Nope but we'll call Eufy support on your behalf and they will call you. We will also call you to follow up. I've been a customer service manager a lot of years and this is where employees can kill you. This Amazon person made me multiple promises. It's been a week no call from Eufy, no call from Amazon. You just turned 4 stars into 1 and if this is all the longer the batter lasts don't bother because the replacements are $25 to $30 bucks depending on the brand. I'm not spending a hundred bucks a year on batteries and this thing should be under warranty. After 3 days I ordered a new battery and Rosie is running again but I'm no longer pleased and the next time I'll buy another brand. If if this battery doesn't last the whole thing goes in the trash and I buy something else. I run this every day maybe the batteries won't take that I don't know. But if you're going to run it every day buy something else. This didn't last long enough at all. I wanted to wait a while to be sure I had a good sampling and could post a fair and useful review. It's been 90 days now. We have two large (bigger than standard) labradoodle puppies. 85 and 50 pounds and they're 1st generation so they shed a lot. They also, being puppies, have tore the yard up so it is basically a mud pit and they wrestle, run, and fight constantly. They put a lot of dirt and hair on the floors and in the air. We run "Rosie" every day. Yes my wife named it. It does an amazing job on our hardwood floors and throw rugs. It gets all the hair and an incredible amount of dust and dirt. What I mean by that is we can run our Dyson or the Shark Pet vacuum and then run Rosie and the chamber will be full of dust and dirt when she's done. It's almost disconcerting to know our very expensive upright vacuums leave so much behind. It also has the unadvertised ability to buff our hardwood floors. They shine when she's done and the beater brush is showing no signs of damaging the finish on our floors. I would disagree with some of the reviews and even the manufacturers assertion that it doesn't work well on dark floors. Our hardwood floors are a dark reddish brown. The device works great on them and as I said when it's finished they shine. We have agreed we will never be without one and love this device. It does everything it has been advertised to do and more. Also it is set to automatic power and runs longer than the advertised time on a full charge. We get about 2 hours and 15 minutes. We've put down an additional 6 throw rugs for the rainy snow season in the path where the dogs run when they come in and the time has dropped to around 90 to 100 minutes. Still long enough to cover everything well and more than once. It does keep going until it needs a charge it doesn't just run and go back to the dock. I've noticed in the open areas like our living room it might hit that 2 or even 3 times. The floors are like glass after that. Now for the negatives, and these are not deal breakers I'm just being fair. The dirt and dust I referred to is new to us. we recently moved from Illinois to Ohio. In Illinois the dirt is black. Here it is red or a very light brown. The vacuum gets externally dirty. It gets covered with dust/dirt and does not look good. The device is black and the dust is light colored and is readily apparent. I don't want to put it away all the time or for company so thats a problem for me and more cleaning which is not advertised so I'm mentioning it. Secondly it needs to be emptied every use or every other use. They are all like that except some of the super expensive robot vacuums so I wouldn't mention it except for my third negative. It is hard to clean from a mess standpoint. Not so much with the pet hair but with the dust. When you dump it the dust goes everywhere. Unless you have an empty trash can so you can get it way down inside when you're done the garbage can lid and sometimes the floor around the garbage can is clearly dusty from emptying the vacuum. The filters need to be removed at least every other running and they are also a big dusty mess. I also don't believe they will last as long as advertised. I have an air compressor in the garage and a hand held electric air compressor and use those to clean the filter. The foam piece I rinse in the sink. I don't think that someone without access to those tools is going to get the life out of the filters thats advertised. The device comes with a set of replacement filters and the rotating brushes. Not the beater bush though. Our unit is 3 months old. I had to replace the filters at about 40 days and tried to make them last a little longer this time but it hasn't worked out. The outside of the device is filthy. I believe this is due to the filters. The brushes have lasted longer than the suggested replacement time. They are 90 days old and still look like new. Last and has been a rare negative. The device will get stuck under things. Once I learned what the obstacles were in our home it was easy to fix. Some areas I blocked with rolled up moving blankets. I pull the chairs out from under the kitchen table to allow room for it to maneuver. If I don't it gets under there and spends way too much time cleaning and trying to get out. I'd rather it spend less time under there so it can do the whole cleaning area and have power left to do it again. I had the problem spots corrected and figured out within the first 30 days. I've read some units have a tape or something the vacuum will sense and avoid. I wish this unit had that but then again at this price point that is probably an unfair expectation. So those are the pro's and con's we've encountered. The con's are all minor irritants and not a reason not to buy the device as all of these devices are prone to these issues except one or two of the very very expensive units. To repeat what I said earlier this device has worked out so well we have decided that we will never be without one and that when the time comes to replace her we will not feel bad about spending the money for a high dollar unit as it is worth it. Time is worth more to us than money and this thing saves us a great deal of time. It does great job, has done no damage to anything, and if it weren't for the clean up issues would be a five star review. I hope this helps someone make an informed decision and I hope you buy one. It's an amazing little machine, stands up to all the reviews, and truly is the best bang for your buck in robot vacuums.

Amazing cleaning partner!! Love!
Color: Black - 03
This is my first robot vacuum and I'm in love with it! I love being able to be doing something else, folding laundry, making dinner etc while this is cleaning the floors. Harry, as I've named him, is my cleaning partner. While it by no means replaces the suction on a standard push vacuum It's great at those between cleanings to keep things picked up. We have a dog with long white hair and a cat so hair clean up is always an issue and I'm very ocd about my house being clean. The suction doesn't leave my thick carpet hair free by any means but it's a great help to keep up with it. I read a lot of reviews before buying so wanted to share my experience after having this about two months now and using several times a week. I vacuum the house during the week with Harry and he mops my hard floors on the weekend...and I do a stand up vacuuming with my big vac on the weekend. I hope this helps you! Here are some of my thoughts on how this thing "Harry" works: MOPPING. This feature is amazing!!! And one of the few robo vacs with the option. I love being able to put a little cleaner and water in the bin and let it do its thing. This model doesn't have the ability to map rooms you want it to clean in (if your carpet butts up to hard floors) but I found an easy solution. As my bar stools and garbage cans need to be moved so Harry can mop everything I just use them to block off my great room so it stays on the hard floors. Leaves my floors pretty dang clean and smelling good, while I do other things! You can also buy magnetic tape to block room's but I don't see the need with my blocking technique, and I just close the doors to my carpeted bedrooms. Wet the pad on the bottom before starting to help get it going, the water in the container slowly seeps out so getting the pad wet ensures its starts mopping right away. Will need to refill water bin about every 30 min. I use a little fresh scent pine sol then fill rest with water. SUCTION. The suction is great on hard floors gets everything up. The side sweeper is great against walls and cabinets. I have thick carpet so didn't expect it to suck everything up but it does a great job. Still leaves my dogs hair behind a bit. I use my big vacuum once a week for a deeper cleaning. For what it is this little guy does pretty good! OBJECT AVOIDANCE. My husband wanted the model that is twice the price or more that has the laser mapping eye. Not sure how that works but for the price this works just great! It senses something before running into it, slows down then gently bumps it and turns around. Also the low profile is great for getting under beds and dressers where hair and dirt hides, love this! Not saying I wouldn't like the laser mapping eye but didn't want to spend 2x+ the amount and this has proven to work really well. NAVIGATION. While I know other models are more technologically advanced again for the price this works great. It vacuums in straight lines which is great for my ocd. If it runs into an obstacle it can get off track from those lines as its works it's way around things. Sometimes it seems confused and goes back and forth in the same area, but generally works itself out and keeps going. I would like to be able to control where it goes in the house but not available on this model, but again for the price I'll say I don't really mind. I just let it go where it wants or shut it in an area if I want it to stay in there. BATTERY. The battery is pretty great. Runs for 2+ hours before needing to charge. I have a 2,700 sf rambler and it can't get through the whole house before needing to charge. If it were a tad more efficient in navigation it probably could, but does spend some time trying to figure out where it is and where to go. I just charge it and set it loose on the other side of the house. MAP/APP It has a map feature that is only to show you where it went during the clean up. You can't interact with the map or tell the vaccum to work in certain areas with it. But I knew this when I bought it so wasn't expecting that. If you are looking for a vacuum you can tell where to go then spend more for the upgraded models. I don't feel a huge need for this, works fine for me. The app is more for basic settings, you can turn it on and off and see what it's doing, battery life, have it call out to you if you can't find it. You can hook to Alexa which is awesome to say "tell Harry to start" and off it goes. Again you can't control its direction or rooms work the app it's more for stop/go and basic settings and maintenance. STAIRS. We have a sunken living room with a step.down the whole length if the room, hasn't fallen once. Its senses the step, and moves away, kinda bounces along the step turning, Sensing and moving it's way along it. Perfect. DUST BIN. this model has one of or the largest bins on the market, its holds a lot for hours of work. It's easy to access right on top, open the side and empty. The filter pops out so you can clean it, found taking outside and bumping on concrete left a good amount of dirt. NOISE. I think it's pretty quiet for a vacuum cleaner. I only have my noisy stand up to compare to and its much quieter than that. It's basically just the light suction noise, I don't hear the motor at all. OVERALL. For the price this is the best investment I could have made to help keep my house clean during the week while I'm busy with work. I love being able to start it and walk away accomplishing other things and come back to clean floors. It's a little misguided at times but nothing bad. I'm sure more expensive models are a bit more intelligent but for $350 this is the best option out there. I would highly recommend if you need a helping hand. My favorite feature is the mopping, I hate mopping floors and this does the job for me! This thing is amazing and I can't believe I've never had one, will never be without now! Happy cleaning!!

Vacs AND Mops Great!!! We love her! 🩷
Color: White
This little machine (lovingly named Yvette) does an amazing job!! I was skeptical of its mopping capabilities after reading mixed reviews, but I can attest that it does a great job lightly mopping (not mega gross sticky messes, just water stains and normal dirt). I included a video. The vacuum function is also fantastic. The only issue so far was a chair with a bar that goes across the floor. She got stuck on it and had to rescued. While she navigates extremely well in our single-story home with tile, vinyl flooring & low pile rugs, she does ruffle up the rug corners a bit on the lighter-weight ones. I just pick them up and toss them in the wash while she cleans. I will say you need to pick up your charger cords! She will swallow them whole and keep on going 😂 The good news is, the roller comes out easily and nothing was damaged. The cord was fine also. I think this was a great investment. It is a little loud, but nowhere near as loud as a standard vacuum cleaner. Just make sure to pick up toys, cords, dog toys…just like you would if you were doing the work, and all will be fine. I ordered disposable vac bags and a kit with extra mop cloths, roller, cleaning tool and brushes. It only cost about 20$. Well worth it!!! The battery life is good, but I do mop in the “zone” function rather than the whole house. That way I can put a new mop pad on and top off the water and Yvette can take her union break (charge up) before going on to the next area😉. She does manage to vacuum the entire house without needing to charge, which is awesome.
